Interesting Sleep Fact

There’s one sentence that sends shivers down the spine of every sleep expert around the country.

‘Late night snacking.’

Chocolate, ice cream, crisps, soft drink, donuts (I’m looking at your dad), even coffee.

We all do it.

Some more frequent than others.

But there’s a catch that many don’t realise when we indulge like this.

Late night sugars and snacking are a BIG contributor to poor sleep, restlessness and general tiredness.

Ultimately, our cravings become more than just a bad dietary choice.

What is clear is that late night snacking impacts your sleep performance.

Something we care deeply about at COZO.

So like your sweet grandma who loves you unconditionally and wants the best for you, we’re here to help.

We won’t tell you to stop late night snacking … because where’s the fun in that??

What we are going to do is talk about WHAT kind of snacks to eat.

Here is our snack criteria:

  • a. Healthy

  • b. Actually tastes good

  • c. Helps you fall asleep quicker

  1. Kiwi Fruit 🥝

Outside of Kiwi fruit being absolutely delicious (criteria b ✅), it contains sources of Melatonin, which plays an important role in your circadian rhythm regulation.

If you don’t know what the hell your ‘circadian rhythm regulation is’ - it’s like an internal clock in our bodies that tells us when to wake up, feel tired, or go to sleep, based on a 24-hour cycle influenced by light and darkness.

Eating kiwi fruit before bed reminds your body that bedtime is near and helps you get to sleep faster.

  1. Cherries 🍒

Similar to Kiwi fruit, Cherries contain a small dosage of Melatonin.

Sweet and Tart cherries seem to be the two most packed with Melatonin.

Swap out the Cherry Ripe 🍫 for plain cherries 🍒 for a health kick and a better sleep!

  1. Almonds 🥜

Almonds help the body produce GABA, which helps promote calmness, reduces anxiety, stabilises blood pressure and promotes restful sleep.

Nuff’ said.

  1. Bananas 🍌

Bananas are the GOAT fruit when it comes to nutrients to help sleep performance.

They are rich in sleep promoting nutrients like magnesium, tryptophan, vitamin B6, carbs and potassium.

One medium sized banana (126g) contains enough of the nutrients listed above to make a meaningful impact.

Add a banana or a banana smoothie to your late night snack routine.


There you have it.

Sleep Hack Of The Week

“How do I know if I’m actually getting enough sleep?”

I get this question all the time.

And, outside of how you feel when you wake up each morning (which can be based on a range of factors), this isn’t easy to answer.

Clearly if you wake up feeling tired you probably didn’t get enough sleep.

But that’s not always the case.

I don’t know about you, sometimes I’ll feel energised and ready to attack the day even though I know I didn’t get enough hours.

The same is true the opposite way.

A long night of sleep, but exhausted and tired the next day.

The best way to answer the question?

Technology, of course.

After extensive research, here are the top sleep tracking devices and technology to help clear it up:

  1. WHOOP

  • What it is: A fitness tracker wristband designed for athletes and fitness enthusiasts that can track your sleep performance at night.

  • Differentiates by: Focuses on recovery and readiness, providing insights to optimise physical performance. It uses sleep data to inform users about their body's readiness for activity. More focused on the fitness angle.
